Flexural and shear strengthening of RC beams with composites materials: the influence of cutting steel stirrups to install CFRP strips [PDF]

, 2009
[Excerpt] Introduction: Experimental [1], numerical and analytical [2] research reveals that as larger is the height of the cross section of Carbon Fiber Reinforced Polymer (CFRP) strip, as more effective is the Near Surface Mounted (NSM) technique for ...
